We consider the transfer pricing decision for a multidivisional firm with an upstream division and multiple downstream divisions. The downstream divisions can independently determine their retail prices, and decide on whether or not they will purchase from the upstream division at negotiated transfer prices. To allocate the firm-wide profit between upstream and downstream divisions, we construc...

I consider an upstream supplier that supplies an input to an independent downstream firm and in addition sells the final product to consumers. I find that the upstream supplier cannot implement the monopoly outcome without imposing maximum resale price maintenance (RPM). RPM increases social welfare if consumers’ valuation for the final product of the downstream firm is high, and decreases soci...

I analyse the effects of a downstream merger in a differentiated oligopoly when there is bargaining between downstream firms and upstream agents (firms or unions). Bargaining outcomes can be observable or unobservable by rivals. When competition is in quantities, upstream agents are independent and bargaining is over a uniform input price, a merger between downstream firms may raise consumer su...

OBJECTIVES The purpose of this study was to characterize the hemodynamic force acting on plaque and to investigate its relationship with lesion geometry. BACKGROUND Coronary plaque rupture occurs when plaque stress exceeds plaque strength. METHODS Computational fluid dynamics was applied to 114 lesions (81 patients) from coronary computed tomography angiography. The axial plaque stress (APS...

In many natural systems, the physical structure of the landscape dictates the flow of resources. Despite mounting evidence that communities' dynamics can be indirectly coupled by reciprocal among ecosystem resource flows, our understanding of how directional resource flows might indirectly link biological communities is limited. We here propose that differences in community structure upstream s...

Unidirectional water flow results in the downstream-biased, asymmetric dispersal of many riverine organisms. However, little is known of how asymmetric dispersal influences riverine population structure and dynamics, limiting our ability to properly manage riverine organisms. A metapopulation of the freshwater pearl mussel Margaritifera laevis may be sensitive to river currents because mussels ...
